Problems solved by technology

Traditional filter elements are more effective in filtering large particles of fine dust, such as ordinary melt-blown non-woven filter elements, but the adsorption effect on neutral particles such as aerosols or organic particles is not good. The key is that the particles in the air after filtration A lot of dust and bacteria are left on the filter paper of the filter element, which can easily cause bacteria to grow

Abstract

The invention discloses a filter for a heat exchanger and a method for making the filter element thereof. The filter includes a filter box, a coarse-effect filter element and a secondary filter element. Air inlets and air outlets are respectively arranged at both ends of the filter box. The coarse-effect filter element is installed On the side near the air inlet in the filter box, the secondary filter element is installed on the side near the air outlet in the filter box. The secondary filter element is made of foam activated carbon as the skeleton, embedded with porous ceramsite filter treated by nano-silver or nano-titanium dioxide adsorption. material composition. The secondary filter element of the present invention uses foamed activated carbon as the skeleton. The foamed activated carbon not only has a very large internal surface area ratio, but also has the adsorption characteristics of activated carbon. In addition, the complex and identical three-dimensional network structure inside the foamed carbon serves as the filter element skeleton itself. It has a very high filtering effect. In the present invention, a porous ceramsite filter material treated with nano-silver or nano-titanium dioxide is also embedded in it, so that the filtration efficiency is high, and it can also inhibit and kill bacteria.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a filter for heat exchangers and a method for making filter cores thereof. Background technique [0002] A heat exchanger is a device that exchanges heat between the introduced outdoor air and the exhausted indoor air. For example, in winter, the discharged higher greenhouse gas can be used to heat the introduced lower greenhouse gas, while in summer it can be heated. Utilize the exhausted indoor air after being cooled by the air conditioner to absorb the heat of the higher temperature outdoor air to reduce its temperature. Generally, the air will be filtered first during the introduction process, and the filter element is generally used for filtration. There are many types of existing filter elements, and the air contains a lot of particles, which can be roughly divided into charged particles, neutral particles (uncharged particles) or organic particles and inorganic pa...
